How to Play (Quick Start)

Your Turn

On each turn, you place one stone on any empty position. Choose between two stone types:

Stone TypeWhat It Does
ResonantProjects strong influence (10.0) up to 3 positions away. Use for building territory.
PhaseProjects weaker influence (6.0) up to 4 positions away, but has 75% chance to disrupt opponent's influence. Use for attacking.

Stone supply is unlimited—choose freely each turn based on your tactical needs.

How Influence Works

Each stone radiates influence outward. Influence weakens with distance:

  • Adjacent positions receive nearly full influence
  • 2 positions away receives reduced influence (~80% of previous)
  • 3+ positions away receives further reduced influence

You control a position when your total influence there exceeds your opponent's. The bigger your lead, the stronger your control:

Territory TierWhat It Means
StrongLarge influence advantage—secure territory
WeakModerate advantage—vulnerable to contest
ContestedSmall advantage—could flip with one stone

Territory Entrenchment: Established territories become harder to disrupt as the game progresses:

  • Early game (turns 1-10): Stones project weaker influence (starting at 30%, scaling to full strength)
  • Strong territories resist Phase stone disruption—85% of disruption effect is blocked
  • Weak territories resist moderately—70% of disruption effect is blocked

This means early territorial claims matter. If you let your opponent establish strong territory early, it becomes increasingly costly to contest later. Conversely, protecting your early gains pays compounding dividends.

Territory Control Example:

    Your Stone [R]               Opponent Stone [P]

▼ ▼
· · · · · ·
· ▓ ▓ · · ░ ░ ·
· ▓ R ▓ · · ░ P ░ ·
· ▓ ▓ · · ░ ░ ·
· · · · · ·

▓ = Your territory (strong near stone, weaker at edges)
░ = Opponent territory
· = Neutral/contested

Where influence overlaps → territory is contested
The player with MORE total influence at a position controls it

How to Score Pattern Points

Patterns: Form geometric shapes with your stones inside territory you control:

PatternShapePoints
TriadThree adjacent stones forming a triangle~10 points
LockFour stones in a diamond (center + three corners)~15 points

Pattern Examples:

    TRIAD (~10 pts)              LOCK (~15 pts)

● ●
/ \ /|\
●───● ● │ ●
\|/
3 stones, all ●
mutually adjacent
4 stones in diamond:
center + 3 corners
(all adjacent to center)

Key Rule: Patterns only count if they're inside YOUR territory. Stones placed in enemy territory won't form scoring patterns.

Territory: You earn small points each turn based on how much territory you control.

Capture Warning: If your opponent takes more than 50% of a pattern's territory, you lose the pattern's full point value—and they gain half of it. Protect your patterns.

Winning

Matches are best-of-three epochs (games). Each epoch has a set number of turns (typically 35).

  • Win an epoch by scoring 15% more than your opponent when turns run out
  • Win 2 epochs to win the match
  • Close scores result in a draw for that epoch

Special Events: Resonance Storms

1-3 times per epoch, resonance storms randomly shift influence across the board. You'll see upcoming storms in the event display. Diversify your position—don't put all your influence in one region.


Game Overview

TriDyak is a custom-designed strategic board game with AI engineered using the same techniques used in world-class Chess and Go programs:

  • 750,000+ opening book positions — Like Chess grandmasters, the AI draws on a library of studied moves rather than guessing. You face intelligent play from the first stone.
  • Neural network evaluation — The AI "sees" the board holistically, recognizing patterns and evaluating positions the way experienced players do.
  • Adaptive difficulty — Three skill levels (Easy, Medium, Hard) with automatic escalation if you're winning too easily.

If you enjoy Go, Hex, or Hive, you'll find TriDyak familiar yet refreshingly different.

If You've Played Other Abstract Strategy Games

TriDyak draws inspiration from several classic games you may know:

From Go — TriDyak borrows abstract territory control and deep strategic complexity. But where Go scores territory by surrounding empty space with stones, TriDyak uses influence projection—your stones radiate control outward, and territory is determined by who has stronger influence at each position.

From Hex — TriDyak uses a hexagonal grid and shares the "place once, never move" mechanic. But where Hex has a single goal (connect your two sides), TriDyak combines territory control with pattern completion—you're building influence networks while trying to form scoring patterns.

From Hive — TriDyak shares the concept of multiple piece types with different abilities. But where Hive pieces move constantly across an infinite plane to surround the opponent's Queen, TriDyak stones are permanent once placed—your strategic decisions are final.

"This looks like Go—how is it different?"

In Go, you surround empty space to claim it. Territory is binary: yours or not yours. Stones can be captured and removed from the board.

In TriDyak, you don't surround—you radiate. Each stone projects influence outward that weakens with distance. Territory isn't binary; it exists in tiers (strong, weak, contested) based on who has more influence at each position. Your stones are never removed—but your territory can shift as your opponent projects competing influence.

This creates a fundamentally different game feel:

  • Go rewards encirclement — you build walls to claim space inside them
  • TriDyak rewards positioning — you place stones where their influence overlaps and reinforces

The two stone types add another layer Go doesn't have. In Go, every stone is identical. In TriDyak, choosing Resonant (stronger, shorter range) vs Phase (weaker, longer range, disrupts opponent) is a tactical decision on every turn.

Finally, TriDyak's best-of-three epoch structure means a single game doesn't decide the match. You can lose an epoch, adapt your strategy, and come back.


How TriDyak Works

The Board

A diamond-shaped hexagonal grid with 397 positions. Influence radiates outward from placed stones.

The Pieces

Two stone types create different influence patterns:

Stone TypeRangeBase InfluenceSpecial Effect
Resonant Stones3 positions10.0Strong, permanent territory expansion
Phase Stones4 positions6.0Disrupts opponent influence (75% chance), effect fades over ~3 turns

Influence decays with distance—a stone's effect weakens the farther you get from it.

Phase Stone Timing: Phase stone disruption effects are temporary—they decay over approximately 3 turns. This means early-game phase placements lose effectiveness by mid-game. Time your disruption plays for when they matter most, not as opening moves.

The Goal

Control territory through influence projection. Victory comes from:

  • Forming required patterns in controlled territory (triads: 3 pieces, locks: 4 pieces)
  • Winning more epochs than your opponent (best of 3)
  • Balancing territory expansion with pattern completion

Best-of-Three Epochs

Matches consist of up to three epochs. Each epoch is a complete game:

Epoch TypeTurns per EpochGameplay Style
Standard35 turnsBalanced strategic play
Turbo20 turnsFast, aggressive games
Marathon50 turnsExtended strategic development

Epoch Rules:

  • Win an epoch by having 15%+ higher score when turns run out
  • Board resets between epochs
  • Win 2 epochs to win the match
  • If tied 1-1, epoch 3 decides (or cumulative score if all epochs draw)

Resonance Storms

Each epoch includes 1-3 resonance storms—random events that disrupt the board state. Storms add unpredictability and prevent purely calculated play from dominating.

Storm TypeFrequencyEffect
Influence Shift50%Redistributes influence across contested territories
Resonance Boost30%Amplifies one player's existing influence patterns
Pattern Disruption20%Weakens established patterns, creating openings

Storm Strategy:

  • Storms favor players with diversified positions—don't put all your influence in one region if you receive a storm warning
  • The leading player often benefits less from storms than the trailing player

The AI Opponent

TriDyak's AI is purpose-built.

Opening Book: 750,000+ Positions

An opening book is a database of studied positions and their best responses—the same technique used by world-class Chess engines like Stockfish and professional Go programs like AlphaGo. Rather than calculating every position from scratch, the AI draws on accumulated knowledge of what works.

TriDyak's opening book contains over 750,000 catalogued positions:

  • Bayesian confidence scores — Statistical certainty levels for each move recommendation
  • Win rate tracking — Historical success rates inform move selection
  • Continuous learning — The book grows as new games are played
  • Strategic classification — Positions tagged by opening type and recommended strategy

This approach mirrors how human experts develop opening repertoires—through study, pattern recognition, and accumulated experience.

Custom Neural Network

A neural network (~18,000 parameters) trained specifically on TriDyak:

  • Four areas of focus: move quality, strategy alignment, strategy effectiveness, pivot signal
  • Learns from self-play games through continuous training
  • Understands TriDyak-specific positional concepts
  • Evaluates board states in milliseconds

What this means: The AI understands the game. It evaluates positions holistically.

Bayesian Confidence Scoring

The AI knows how confident it is in each position:

Confidence LevelWhat It Means
Very HighPosition is clearly evaluated, optimal play known
HighStrong understanding, few uncertainties
MediumMultiple plausible approaches, position is contested
LowNovel position, AI is exploring
Very LowUnknown territory, AI is learning

What this means: Novel positions challenge both players.

Adaptive Difficulty

The AI adjusts to challenge you appropriately:

DifficultyAI Behavior
EasyPicks from top 5 candidate moves (introduces exploitable mistakes for learning)
MediumPicks from top 3 candidate moves (balanced, competitive play)
HardAlways picks the best evaluated move (full strength)

The AI uses the same strategic intelligence at all levels—the difference is execution precision. Lower difficulties create patterns you can exploit while learning.

Auto-Escalation: If you dominate an epoch by 30%+ margin, the AI automatically escalates to the next difficulty level. This prevents farming easy wins.

What this means: The AI matches your skill. Learn at Easy, compete at Medium, test yourself at Hard.


Strategic Concepts

The Three Core Strategies

The AI uses three distinct strategic approaches. Understanding when to use each is key to strong play.

Expansion — Build your network outward

  • Place stones adjacent to your existing territory
  • Use Resonant stones for network building (stronger, shorter range)
  • Spread out from center early—controlling more board area creates options
  • Best in: Early game (first 20% of turns)

Disruption — Interfere with opponent territory

  • Place stones inside opponent territory to weaken their control
  • Target their strong (uncontested) territories for maximum impact
  • Use Phase stones for disruption (wider range, 75% chance to disrupt)
  • Best in: Mid-game when positions are contested

Consolidation — Strengthen what you have

  • Protect territories you're winning
  • Block opponent pattern formations
  • Use when you have a score lead you need to protect
  • Best in: Late game when defending a lead

Game Phase Strategy

Early Game (turns 1-7 in Standard)

  • Focus on expansion—spread influence across the board
  • Avoid committing to one area; keep options open
  • Resonant stones build stronger initial networks

Mid-Game (turns 8-21 in Standard)

  • Disruption becomes highly effective—actively contest opponent territory
  • Don't play reactively; be deliberate about where you place
  • The player who controls the contested zones usually wins

Late Game (turns 22-35 in Standard)

  • Pattern completion matters most—hunt for triads and locks
  • Protect your existing patterns from capture
  • Every stone counts; don't waste moves on low-value positions

Stone Selection

SituationBest StoneWhy
Building your networkResonantStronger influence (10.0 base), good for territory
Disrupting opponentPhase75% disruption chance, wider range (4 vs 3)
Contested zonesEitherResonant for control, Phase to deny opponent
Pattern completionResonantStronger territory bonus for completed patterns

Pattern Formation

Triads — Three of your pieces in a valid triangle

  • Lower point value but easier to form
  • Can complete anywhere on the board
  • Good for steady point accumulation

Locks — Four pieces with center + three corners

  • Higher point value but requires precise placement
  • The center piece must be yours; corners extend outward
  • Worth pursuing when you have board control

Pattern Tips:

  • Patterns in strong (uncontested) territory score more
  • Opponent can capture your patterns by taking the territory
  • Threatening multiple patterns forces difficult defensive choices

How to Play Defense

New players often focus entirely on expansion and pattern formation, neglecting defense until it's too late. Defense in TriDyak isn't passive—it's about protecting what you've built while denying your opponent's plans.

Why Defense Matters:

  • If your opponent captures more than 50% of a pattern's territory, you lose the full point value and they gain half
  • Patterns only score if they remain in your controlled territory
  • An undefended lead can evaporate in a few turns

Defensive Move Types:

Defensive MoveWhen to UseStone Choice
Pattern blockingOpponent is 1-2 stones from completing a triad/lockPhase (if in their territory) or Resonant
Territory reinforcementYour weak territories are being contestedResonant (stronger influence)
Disruption placementOpponent has strong uncontested territoryPhase (75% disruption chance)
Adjacency defenseProtect existing patterns from captureResonant adjacent to your patterns

Recognizing When to Defend:

  1. Score lead — If you're winning, consolidate. Don't overextend into opponent territory when you can protect what you have.

  2. Opponent pattern threat — Watch for 2 opponent stones in triangular formation. The third position is a blocking priority.

  3. Territory decay — Undefended territories lose influence over time. If your strong territories are becoming weak, reinforce them.

  4. Mid-game pivot — Around turn 12-15 in Standard, evaluate whether to continue expanding or shift to defense based on board state.

Defensive Stone Selection:

  • Use Phase stones when placing inside opponent-controlled territory to disrupt their influence network
  • Use Resonant stones when reinforcing your own territory—Phase stones can accidentally disrupt your own networks
  • Avoid Phase stones in neutral or your own territory unless specifically targeting adjacent opponent stones

The Consolidation Pattern:

When defending a lead:

  1. Identify your weak territories (areas where your influence is contested)
  2. Place Resonant stones adjacent to your strong territories to extend them
  3. Strengthen weak territories before opponent can flip them
  4. Block any opponent pattern formations that threaten your controlled areas

Common Defensive Mistakes:

  • Ignoring opponent patterns — A single completed triad in opponent territory can swing the score significantly
  • Over-extending — Building new territory while existing patterns are vulnerable to capture
  • Phase stone misuse — Placing Phase stones in your own territory, disrupting your own influence networks
  • Reactive-only defense — Waiting until opponent is about to score before defending; by then, options are limited

Scoring System

Your score comes from multiple sources:

Score ComponentDescription
Territory ControlBase points for owned territories
Pattern CompletionBonuses for forming triads and locks
Territory TierExtra points for strong (uncontested) territories
Network EffectsBonuses for connected territory networks
Pattern CapturePoints lost when opponent captures your patterns

Territory Capture and Point Transfer

Defensive play matters. When your opponent captures territory containing your patterns, you don't just lose—they gain:

  • If your opponent takes more than 50% of a pattern's territory, you lose the full point value of that pattern
  • The opponent gains half those points as a capture bonus
  • This makes protecting established patterns as important as forming new ones

This mechanic rewards aggressive territory contestation and punishes over-extension without defense.

Epoch Victory: You win an epoch by having 15%+ higher score than your opponent when turns run out. Close scores result in draws.


Tips for Improvement

  1. Study your losses — Where did influence shift? What pattern did you miss?
  2. Learn the openings — Center control creates winning chances
  3. Think in influence — See the board as territory radiating outward
  4. Calculate before moving — Check what patterns your move enables (yours and opponent's)
  5. Exploit novel positions — Unconventional openings can throw off the AI's prepared responses
  6. Practice consistently — Regular play beats occasional marathons

Historical Note

TriDyak dates to the early Secundus Floreo era—the Cosmos-wide civilization that flourished after humanity's first stellar expansion.
